String Quintet in E flat major, op. 4

The String Quintet in E♭ major, Op. 4, was composed by Ludwig van Beethoven in 1795. It was adapted from his Octet, Op. 103, which, despite its high opus number, was in fact composed by Beethoven in 1792/1793 but was published only in 1837, ten years after the composer's death. The Quintet was published in Vienna in 1796.
